66 -- ENVIROMENTAL STRESS SCREENING MECHANICAL VIBRATION SYSTEM SOL N68335-96-R-0118 DUE 050896 POC P. Edwards Code 213PE, (908) 323-5208. Buyer/Contracting Officer is J. Fackenthal. The Naval Air Warfare Center Aircraft Division Lakehurst, (NAWCADLKE) intends to procure one (1) each an Enviromental Stress Screening Mechanical Vibration System. The specification states the requirements for a mechanical vibration system to be used at the Enviromental Test Laboratory (ETL) operated by the Product Evaluation and Verification Division, Support Equipment and Aircraft Launch and Recovery Department, NAWCADLKE. The vibration system will be configured in a way that it can be used for ENVIROMENTAL STRESS SCREENING in conjunction with a Government owned temperature/humidity/altitude/chamber as well as independently of the chamber in a stand-alone mode. The existing Government owned chamber is made by RUSSELLS TECHNICAL PRODUCTS (Holland, MI), Model #RHD-125-2 (60C)-5 and maybe made available for site visit. The vibration system provided shall be supplied as a fully operational TURN-KEY system. Connection of all utilities will be done by the Government. As a minimum the contractual obligations required by this specification are summarized as follows: (1) Provide a complete mechanical vibration system consisting of an exciter (shaker), slip table for horizontal vibration mode, power amplifier. The shaker shall be configured to permit operation with the Government owned chamber in a vertical piggy-back configuration as well as separately and independently in a stand-alone vertical and horizontal mode when used with the slip table. (2) An automatic digital vibration control and analysis system for sine, random, sine-on-random, random-on-random vibration, shock, signal analysis and Shock Response Spectrum (SRS) testing. The controller shall also have provision for remote control, integration and communication with other enviromental testing equipment such as thermal, and humidity chambers. The controller shall include a printer such as an HP laser jet. (3) The vibration controller/analysis system shall consist of 12 input channels complete with active signal conditioning, 12 accelerometers and a portable magnetic tape recorder. (4) Complete installation and interconnection of the system at NAWCADLKE shall be performed by the contractor to include delivery and placement of the system in the designated area (utility connections will be done by the Government). This requirement will be placed as an option item in the solicitation. (5) Complete maintenance and operating documentation shall be provided. (6) A minimum of sixteen man-hours of on-site comprehensive training of Government personnel in the proper use of the equipment shall be provided. (7) Submit an ''Acceptance Test Procedure'' for review 60 days after award of contract. (8) Perform the acceptance testing after installation of the system in accordance with an approved ''Acceptance Test Procedure''. (9) Inform the Government in writing within 60 days after contract award of all utilities required for operation of the system such as: a. Electrical current requirements for the 3 phase 460 volt service. b. Volume of coolant water required and anticipated water temperature rise. c. Compressed air pressure and volume. d. Furnish a general layout drawing which will include utility requiremennts, overall dimensions of equipment, connecting points for utilities. (10) Placement of the system in this designated area. Verify that the mechanical exciter head mates with the Government owned altitude chamber and demonstrate that the digital controller (to which do not require special utilities) performs according to specifications. Verify performance of the entire system after all utilities are installed by the Government. (11) Complete the entire task within 210 days after contract award.
